SADDLE FOR MAINS.

Application filed MarchrZB, 1920.

To ail 'whom t may concern.'

Be it known that I, GEORGE P. WARTCHOW, a citizen orn the United States,residing at Minot, in the county of Ward, State of North Dakota, haveinvented certain new and useful improvements in Saddles for Mains; and ldo hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled inthe'art to which it appertains to mali-e and use the saine.

This invention relates to water distribution, and more especially tomains and pipes; and the object of the same is to produce a saddle whichwill protect the service cock and will serve as a support for the pipeor casing through which a key may be inserted to close the cock. i

Vhen .it is desired to lead a service pipe from a .main into a house orother point where water or gas is to be used, the main is tapped(usually in the side) and a service cock screwed into the hole andclosed, and from this cock the Service pipe is led and is laterconnected with the plumbing of gas system, the service pipe havingitsown cutoil' cock within the dwelling. This service cock in cities isusually at or near the curb line and issuimounted by a curb box having acover at the ground level, so that the authorities may lift the coverand insert al key and close the cock to cut o the water at a point asnear the main -as possible. In

smaller cities and towns the inain may not be so deep and thecorporation cock 1s not always so well protected, and it is the purposeof the present invention to provide a Y device in the nature of asaddle'which can be clamped over the main and which has one end'shapedso as to protect this cock, as the device will sustain a considerableload in case the same should be thrown upon it by vehicles passing overthe main, perhaps when the soil was soft.

Details are set forth below and shown in the drawings wherein:

Figure 1 is a perspective view from what might be called the front sideof the main showing the entire structure in place.

F ig. 2 is a perspective view from the rear side, the upper portion ofthe casing being broken away and the key shown ready to be inserted.

Fig. 3 is a perspective view of the saddle inverted.

Specification of Letters Patent.

Patented Sept. 28, 1920. serial N. 368,058.

Fig. l is a sectional detail showing the service cock tapped into themain.

' The letter M designates in the present instance a water main, and C isa service cock which has been tapped into one side of the same and fromwhich is to be led a service pipe as indicated in Fig. 1 at P.

his invention consists primarily of a saddle havinot a body 1 cut out orarched on its under side so as to lit closely over the upper half of amain of that size to which it is adapted, its rear end being carrieddown in a single leg ortoe 2 having a set screw 3 which can be tightenedup against the main, and its front end being carried down and forked soas to produce arms 1l spaced suhciently to straddle the cock C withouttouching the same. These arms are substantially triangular in side view,and are connected by a web 5 i'iorming a continuation of the body, whichweb and the arms collectively constitute `a three-sided inclosure forthe cock and the parts above it. The web carries an u pstanding sleeve(i, and into this sleeve is inserted the lower end of a pipe 7 which issecured within the sleeve as by lead packing 8, calking, or a screwjoint.l Over the upper end of the pipe 7 is slipped another pipe 9,preferably having a cap 10 at its top which will stand at or near thelevel of the ground.

No novelty is claimed for the cock C, but as usual it is of theglobe-valve type, its plug having a web 11 across its upper end. keystem 12 is disposed between the'arms 4, transversely notched as at itslower end at 13 to fit over said web, and preferably held thereon bymeans of a pin 15 passing Aacross the stem and through the web. The bodyof the stein rises through the casing and its sleeve, and may be squaredat its upper end as shown at 16. In F ig. 2 is shown the ordinary key 17consisting of a long shank with a handle at its upper end and a head 18at its lower end having a squared socket to lit on the squared end 16 ofthe key stein.

In the use of this device, the ground is dug away down to the main, thelatter tapped and the cock inserted and closed, and

the service pipe led away from the cock. The key stem is now applied andfastened to the web of the cock. The saddle is next put in place overthe key stem, its arms passed down astride the cock, and the set screwin its toe tightened. Now the casing weight. 40

is inserted within the sleeve 6 and calked,

screwed or packed atv8, the casing rising to a point about level withthevground, and its cap l() applied. Thereafter the excavation can befilled in and tamped, and later theY plumber can lead'the service pipe Pto the cutoff valvein the dwelling, and connect it When the dwelling isready for occupancy,the city or town authorities open the Vcock C andthe fluid begins to Tlow. It now at any time, by reason oi the failureof the'hou'se owner to 'ipay his water bill, or on ac'coimt of scarcity'o'f water 'in thesupply system, leakage in'the service pipe, orV for'any other reason where the action o'f thel cut-'o'ii valve in the housewould not be suiiici'ent, it bevcomes'necessary or desirable to cut 'offthe iiow-oi vaft'erV as near 'the main as possible, the cap 10 isremoved and a key "17 is 'run down through the casing unti'l`its head 18engages the squared upper end '1'6 oi' the key stein, and when thelatter is turned for a quarter revolution the cock is closed. li theleak or 'other diiiculty had been at a point quite near themai'n orcock, the water could thus be 'cut off' from the surface without thenecessity of digging down through the 'wet ground and against the upwardiiow of Vthe leaking 'water (or gas), so that the advantage of cuttingoff the low before opening up 'the ground at all is obvious. But in theordinary use of the device, the presence of thesadd'le oifer -the mainand with its arms astride the key stemand cock, aiiords a Vprotectionfor 'these parts of lthe water system, because'the saddle if properlymade and applied 'will` sustainv a very heavy Aliso its sleeve 6 aiordsa support for the casing through whichthe key is to VbeV inserted,whether said casing is at the y curb line or not orowhet'her it risescompietel'y tothe surface or not. yThe structure will be by preference'made of rough casting', and in sizes adapted to mains of various gage.

That is claimed as new is:
